The solubility of aldehydes and ketones decreases rapidly with increasing length of the alkyl chain. Explain.
Important Questions on Aldehydes, Ketones and Carboxylic Acids

How would you account for:
Boiling points of aldehydes are lower than alcohols.

Arrange the following compounds in increasing order of their boiling points:


Given below are two statements:
Statement : The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole - dipole interactions.
Statement : The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of -bonding.
In the light of the above statements, choose the most appropriate answer from the options given below :
